Adds the canonical names to the item names of the AEP7 Laser Pistol, AER9 Laser Rifle, DKS-501 Sniper Rifle, and R91 Assault Rifle. Also changes the name of the Hunting Rifle to .32 Hunting Rifle. Requires Operation: Anchorage and changes the names of the versions from that DLC as well.

Name changes are based on the names as listed in the Vault Fallout Wiki at fallout.wikia.com. Some items were not changed; specifically, if the item was not listed as Playable in the GECK, I made no change to the name of the item.

It's best to load this mod early in the load order, before any other mods that alter these particular guns, so that my changes are overridden by the other mod.

FWE compatibility please.

I think that's easier said that done
The problem is this would require compatbility patches for FWE, WMK, EVE and all possible combinations of that. You'd end of up with a bunch of new files.
